Abstract
The invention discloses in a kind of anti-scald spool structure-improved, pass through the shunting of first through hole and the second through-hole, it may be such that the hot gas of high temperature water flow is introduced into space where memory spring, so that memory spring provides extruding force before piston exits valve body to piston, it prevents piston from exiting valve body completely, high temperature water flow is avoided to flow out.
Description
Technical field
The present invention relates to spool technical field more particularly to a kind of anti-scald spool structure-improveds.
Background technology
Memory spring, which has to be heated under compressive state, replys former long ability, therefore be introduced into spool field.Pass through memory
Spring is, it can be achieved that spool blocks automatically in the case where accessing hot water water temperature over-high, so as to which high-temperature-hot-water outflow be prevented to cause to scald
Wound.
Use of traditional memory spring on spool does not design storage chamber, first through hole and the second through-hole, such as
This, memory spring could restore promotion piston motion after piston exits valve body because of water temperature, i.e. piston necessarily now moves back
Go out valve body then to return in valve body so that a part of high-temperature-hot-water outflow, it is impossible to the possibility scalded completely.
Invention content
Technical problems based on background technology, the present invention propose a kind of anti-scald spool structure-improved.
A kind of anti-scald spool structure-improved proposed by the present invention, including：Valve body, piston, memory spring and bonnet；
Valve body first end connection flower pawl, bonnet are mounted on valve body second end；Piston is slidably mounted on valve body second end, piston
Movement locus be inserted into valve body second end；Piston connects bonnet by memory spring；
Valve body periphery is equipped with first flange face and second flange face, has gap between first flange face and second flange face,
Second flange face is located at valve body second end；Valve body is equipped with first through hole, and first through hole is located at first flange face and second flange
Between face；Second flange face is equipped with the second through-hole.
Preferably, the aperture of first through hole is more than the aperture of the second through-hole.
Preferably, the aperture of the second through-hole is less than or equal to 1mm.
Preferably, piston is made of metallic plug body, rubber pad and metal gasket, and metallic plug body and metal gasket are bonded in rubber
The opposite both sides of rubber cushion, memory spring are connect with metal gasket.
In a kind of anti-scald spool structure-improved of the present invention, by the shunting of first through hole and the second through-hole, height may be such that
The hot gas of stream of warm water is introduced into space where memory spring, so that memory spring carries before piston exits valve body to piston
It for extruding force, prevents piston from exiting valve body completely, high temperature water flow is avoided to flow out.
Description of the drawings
Fig. 1 is a kind of anti-scald spool structure-improved schematic diagram proposed by the present invention.
Specific embodiment
Reference Fig. 1, a kind of anti-scald spool structure-improved proposed by the present invention, including：Valve body 1, piston, memory spring 3
With bonnet 4.
1 first end of valve body connection flower pawl, bonnet 4 are mounted on 1 second end of valve body.Under spool conducting state, flow passes through flower
Pawl enters valve body 1, is then flowed out from bonnet 4.Specifically, under spool working condition, periphery is arranged with housing A, and valve body 1 is installed
In housing A, bonnet 4 is mounted in housing A and far from valve body 1.
Piston is slidably mounted on 1 second end of valve body, and the movement locus of piston is inserted into 1 second end of valve body.That is, piston is in movement
In the process, it can be inserted into 1 inside of valve body and block valve body 1, it also can be far from valve body 1, so that valve body 1 is connected.Piston passes through memory spring 3
Bonnet is connected, bonnet 4 and the relative distance of valve body 1 are fixed, and piston is back and forth transported with the flexible of memory spring 3 relative to valve body 1
It is dynamic.
Under spool conducting state, valve body 1 is lived by the water impact piston that flower pawl introduces so as to compress memory spring 3
Plug exits valve body 1；If water flow temperature is excessively high, memory spring 3 restores former length, so as to which piston be pushed to block valve body 1 again.
In present embodiment, 1 periphery of valve body is equipped with first flange face 5 and second flange face 6, first flange face 5 and second
There is gap between flange face 6, second flange face 6 is located at 1 second end of valve body.Specifically, after the completion of spool is assembled with housing A, the
One flange face 5 and second flange face 6 cooperatively form the storage chamber of sealing with 1 outer wall of valve body and housing A inner walls.Valve body 1 is equipped with
First through hole 7, first through hole 7 is between first flange face 5 and second flange face 6.Second flange face 6 is equipped with the second through-hole
8.Piston is inserted into the state of valve body 1, and 1 inner cavity of valve body connects 3 place space of memory spring by storage chamber.
In present embodiment, by the shunting of 7 and second through-hole 8 of first through hole, it may be such that the hot gas of high temperature water flow is advanced
Enter 3 place space of memory spring, so that the forward direction piston that memory spring 3 exits valve body 1 in piston provides extruding force, prevent
Piston exits valve body 1 completely, and high temperature water flow is avoided to flow out.In present embodiment, the aperture of first through hole 7 is more than the second through-hole 8
Aperture, pressure during to increase by 8 air-flow of the second through-hole or flow by the second through-hole 8, so as to improve flow velocity.Second is logical
The aperture in hole 8 is less than or equal to 1mm, flows out larger high temperature water flow to avoid by the second through-hole 8.
In present embodiment, piston is made of metallic plug body 21, rubber pad 22 and metal gasket 23, metallic plug body 21 and gold
Belong to gasket 23 and be bonded in the opposite both sides of rubber pad 22, memory spring 3 is connect with metal gasket.The utilization of rubber pad 22, that is, have
Conducive to the guarantee that piston seals valve body 1 is increased, and be conducive to mitigate the overall weight of piston, so as to improve the spirit of piston motion
Activity.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
